Hi,
Has anyone who tried directional speakers (those that use ultrasound etc to
create audible inteference patters in a "beam of sound" etc) -? If so what
were your experiences - did they work ? Any recommendations on particularly
good ones ?
I am looking at two at the moment (soundlazer and hypersound) - sound lazer
claims to be able to make a sound seem like it is emmiteed by the object
its aimed at - if this is true then I will have lots of fun with that - but
part of me is skeptical......

anyone ?
